Let me take a different tack than the one I took above, where I said "Culture hasn't been a key factor? Au contraire!"
There's that Madonna song, written by Peter Brown and Robert Rans, Material Girl (1984). The chorus is...
'Cause we are living in a material world
And I am a material girl
You know that we are living in a material world
And I am a material girl
The existing technology and industry that is available determines the sort of culture we have. Agrarian societies have agrarian cultures based on agrarian technology. It's not 'no tech' but it does tend to be low tech--the devices used to connect the horse to the plow, the plow, the crop yields, the kind of life that horse power makes possible. Not all that bad. Elsewhere, steam is harnessed to do much more work than a horse can. One day, the steam engine pulls a train out into the hinterlands and the agrarian culture is changed by the industrial technology. Now the farmers sell their crops to distant markets and and can buy things from distant warehouses, which the train will deliver. No more home-spun cloth; now they can get nicer cloth made in a factory. No more clunky locally made boots. Now their boots are made in a factory with big machines, better leather, and standard sizes. Much nicer.
Industrial capitalism has different rules than agrarian agriculture--which is what many countries, including the US, had in the past. Industrial capitalism, in the US or China, depends on the reciprocal movement of production and consumption.
Question: What leads the reciprocal process: consumption or production?
It might be production. I have the technology at hand; I can use it to make shoes. But how many shoes should I make? 1 pair per person per year in this city? My factory can do that quite easily, and it will be somewhat profitable. However, I have the capacity to make 2 pairs of shoes per person per year. At that level, I will make more profit and will get richer. But somehow, I have to convince people that they should buy an extra pair of shoes per person per year.
Fortunately, somebody just invented advertising. I can use advertising to convince people that it is actually a very good thing to have 2 pairs of shoes per person per year--a black work boot and a brown oxford. Next year the ideal will be a black work book, a brown oxford, and something new, an fancy slip-on. And so on.
The shoemaker's factory is humming, he's getting rich, and shoes have become fashion. More, more, more.
Industrial production and capitalism's need for ever-expanded markets creates and drives culture. What used to be an agrarian culture of peasants, yeomen farmers, able hard working men and sturdy resourceful women, becomes a dense urban culture of many people working together, doing all sorts of narrowly defined tasks.
In the industrialized, capitalist urban environment, buying and displaying goods has become more than a habit -- it's an economic necessity. The act of buying and having takes on values that were entirely irrelevant or unimaginable in even a prosperous agrarian society. The mountain of products that the factories produce
must be bought -- whether or not people need or want them. (Or overproduction leads to a depression.)
Industrialized capitalism is a trap. Once a given culture steps onto the treadmill of production and consumption, it's very hard for it to get off without a crash. And, like all good traps, it isn't really visible until it's too late.
